What is the angle between the wind direction and isobars? —Dan Strink, Crete Dear Dan, Isobars on weather maps are lines connecting locations with the same air pressure.

An isobar is a line of constant pressure. These lines are often measured in 2, 4, or 10 millibar increments.

“Where the isobars are closest together, the wind will be the strongest (usually near a cold front or low pressure system) and where the lines are farthest apart, the wind will be lightest (near ...

Dear Tom,What do isobars represent on weather maps?—Mal Wallis, LyonsDear Mal,A bar is a metric unit of pressure and isobars are lines on a weather map that connect points of equal air pressure ...

A bar is a metric unit of pressure and isobars are lines on a weather map that connect points of equal pressure. Since variations in air pressure drive the atmosphere’s winds, isobars also give ...

Hourly weather observations that include sea-level pressure readings are plotted or printed on weather maps that meteorologists can analyze. Isobars are drawn by connecting points having equal sea ...

Isobars that are closer together mean the air is shifting between different pressure areas. Hikers will recognize them as similar to topographical maps, in which more closely clustered lines indicate ...

On the weather forecasts, you often show plots of isobars moving and then seem to indicate that the winds will be running parallel to the isobars. We all know that winds should be perpendicular to ...

Weather map explainer: What are cold fronts, synoptic charts, isobars? CONFUSED by a trough? Don’t know the difference between a low and high? Here’s how to make sense of the weather.
